Rather a Tcl/Tk issue. You may not be aware of the fact that Cygwin's
Tcl/Tk is in reality a set of true *native* win32 binaries. No POSIX
emulation layer at all. That is, tclsh and wish need to find their
libraries with Win32 style paths.

Assuming you are using the latest Tcl/Tk as of today and
bash/zsh/pdksh as your default shell, add this file to your
/etc/profile.d/ :

cat > /etc/profile.d/tcltk.sh
export TCL_LIBRARY=$(/usr/bin/cygpath -w /usr/share/tcl8.4)
export TK_LIBRARY=$(/usr/bin/cygpath -w /usr/share/tk8.4)
^D

Close your shell console and start a new one. Your test programs will
work as expected. If you examine your shell environment, you'll find
the folowing:

TCL_LIBRARY=C:\cygwin\usr\share\tcl8.4
TK_LIBRARY=C:\cygwin\usr\share\tk8.4

This same procedure solves the problem people has had with WinCVS.

Cheers

Alejo
